BPD is playing horrid tricks on you.


I've been through something similar although not walking down the aisle type.


I use fact checking and back it up with evidence.


I make a list of my fears, then I add what evidence supports them and last but not least evidence that disproves them.


I even have an evidence box of mementos to look through and help me. This way I don't need to fact check with bf, as it might get "old" for him.
